Evaluation of Digestibility of Palm Fronds Shaving (PFS) Supplemented with Vitamin B Complex on the Quality of Fermentation by in vitro Method and Degradation Kinetics by in Sacco Method

This study aimed to determine the digestibility value, fermentation quality and degradation rate of palm frond shaving supplemented with vitamin B complex. The design used in this study was a Completely Randomized Design (CRD) consisting of three treatments and three replications. The treatments were as follows: Shaving palm fronds (CON), palm fronds shaving + vitamin B complex 1% (P1) and palm fronds shaving + vitamin B complex 3% (P2). The results showed that the P2 treatment was significantly different from the other treatments (p<0.05) on all parameters observed, including digestibility of dry matter, crude fiber and fiber fraction. The results of the analysis of VFA and microbial protein and the highest acetic acid value were found in the P2 treatment. In contrast, butyrate and NH₃ values were found in the (control) treatment and propionate was found in the P1 treatment. Analysis of the degradation rate showed that the value of dry matter, crude fiber, ADF and cellulose in treatment P2 was significantly different compared to other treatments (p<0.05). Based on the results of the study, it can be concluded that palm frond powder supplemented with 3% vitamin B complex has great potential as a feed additive for ruminants.
